The company didn't pay to get a DD with their logo on it; DDs aren't purchased or anything like that, the CV who awards it chooses it on artistic merit, not on what it signifies. If it was a kitten, you'd say that Sanrio was paying to have work featured.

I think you misunderstand what's happening behind the scenes, and I'd advise you to ask ^ValaSedai about why this was featured. Make sure you use notes, and don't drag it out on the artist's page; they don't need a discussion on "selling out" or whatever you think they did here.
